The European Space Agency's (ESA) Mars Express recently snapped a high-resolution stereo image of the southeast corner of the Amenthes Planum region on Mars, near the Palos crater and the mouth of a well-known sinuous valley, Tinto Vallis.

An international team of researchers studying data beamed back by NASA's Mars Reconnaissance Orbiter have observed seasonal changes on far-northern sand dunes on the Red Planet caused by warming of a winter blanket of frozen carbon dioxide.

An international team of researchers from Los Alamos National Laboratory and the French Space Agency say they have managed to track a trail of minerals that point to the prior presence of water at the Curiosity rover site on Mars.

The data's in from the simulated Mars mission in which six trained astronauts were shut up for a year and a half. And it seems that long-term missions of this kind do indeed lead to problems for the crew.
